Rihanna’s fashion show was eventful, both on and offstage, because we’ve learned one of the models went into labor.

It went down Wednesday night at the Savage X Fenty show in Brooklyn, NY. Slick Woods was super pregnant as she rocked black pasties and lingerie with cutouts … along with nude-colored, thigh-high pantyhose.

The crowd loved it, but just as the 22-year-old walked backstage, we’re told she went into labor. We’re told paramedics showed up to help Slick along. She was taken to the nearest hospital.
